Abstract

A modular teat cup assembly for use with a milking machine for milking cows. The modular teat cup assembly comprises a hollow tubular shell together with a cartridge assembly slidably received within the shell. The cartridge assembly includes a spool-shaped liner and a framework comprising a pair of opposing sleeve members for supporting the liner. The sleeve members are movable between an open position to permit removal and replacement of the liner, and a closed position for supporting the liner therebetween. A cap removably mounted on the bottom of the shell holds the cartridge assembly within the shell and is used to attach a milking tube in the conventional manner. A head piece includes a mouth for receiving a cow's teat, and is snapped onto the upper end of the shell to complete the modular assembly.

Claims

CLAIMS I claim:
1. A modular teat cup assembly for use with a milking machine for milking cows, comprising: a shell including a hollow tubular body having an outer wall and defining a longitudinal axis, said tubular body further including an upper end having a radially inwardly extending upper rim defining an inlet and a lower end having an axially extending lower rim defining an outlet; a cartridge assembly slidably received within the tubular body of said shell and seated against said upper rim, said cartridge assembly including a spool-shaped liner and a framework for supporting said liner, said liner having a hollow tubular barrel with an upper end and a lower end, an upper flange at said upper end and a lower flange at said lower end, said barrel defining a teat-receiving region axially aligned with said inlet and having an outer wall spaced inwardly from the outer wall of said shell to define a vacuum chamber, said barrel deformable between a relaxed profile and a collapsed massage profile; and a cap removably mounted on the lower rim of said shell for holding said cartridge assembly within said shell.
2. The modular teat cup assembly of claim 1 wherein said upper rim includes an annular surface extending perpendicular to said longitudinal axis.
3. The modular teat cup assembly of claim 2 wherein said inlet is tapered inwardly in an axial direction from the outer wall of said shell toward said annular surface.
4. The modular teat cup assembly of claim 1 further including an upper seal between the upper flange of said liner and the upper rim of said shell.
5. The modular teat cup assembly of claim 4 wherein said upper rim includes an annular surface, and the upper seal comprises an annular bead projecting axially upwardly from the upper flange of said liner and a corresponding bead- receiving groove formed in the annular surface of said upper rim.
10
6. The modular teat cup assembly of claim 1 further including a lower seal between the lower flange of said liner and said cap.
7. The modular teat cup assembly of claim 6 wherein said cap includes an annular surface, and said lower seal comprises an annular bead projecting axially downwardly from the lower flange of said liner and a corresponding bead-receiving groove formed in the annular surface of said cap.
8. The modular teat cup assembly of claim 1 wherein said framework comprises a pair of opposing sleeve members movable between an open position to permit removal of said liner therefrom and a closed position for supporting said liner therebetween.
9. The modular teat cup assembly of claim 8 wherein each sleeve member includes an upper collar portion for supporting the upper flange of said liner, a lower collar portion for supporting the lower flange of said liner, and axially extending rigid means interconnecting said upper and lower collar portions.
10. The modular teat cup assembly of claim 9 wherein each collar portion is semi-circular in shape.
11. A liner for use in a teat cup assembly for milking cows, comprising: a hollow tubular barrel having an upper end and a lower end, said barrel defining a longitudinal axis; an upper flange extending radially outwardly from the upper end of said barrel; and a lower flange extending radially outwardly from the lower end of said barrel.
12. The liner of claim 11 wherein said upper flange extends perpendicular to said longitudinal axis.
13. The liner of claim 11 wherein said lower flange extends perpendicular to said longitudinal axis.
14. The liner of claim 11 wherein said barrel, upper flange and lower flange are integrally formed as one piece from an elastomeric material.
11
15. The liner of claim 11 wherein said upper flange includes an upper annular surface, and an annular bead projecting upwardly in an axial direction from said upper surface.
16. The liner of claim 11 wherein said lower flange includes a lower annular surface, and an annular bead projecting downwardly in an axial direction from said lower surface.
17. A cartridge assembly for use with a teat cup assembly for milking cows, comprising: a spool-shaped liner having a hollow tubular barrel with an upper flange at its upper end and a lower flange at its lower end, said barrel defining a teat-receiving region and being deformable between a relaxed profile and a collapsed massage profile; and a framework for supporting said liner.
18. The cartridge assembly of claim 17 wherein said framework comprises a pair of opposing sleeve members movable between an open position to permit removal of said liner therefrom and a closed position for supporting said liner therebetween.
19. The cartridge assembly of claim 18 wherein each sleeve member includes an upper collar portion for supporting the upper flange of said liner, a lower collar portion for supporting the lower flange of said liner, and axially extending rigid means interconnecting said upper and lower collar portions.
20. The cartridge assembly of claim 19 wherein each collar portion is semi-circular in shape.
